Title: Platen and serial printer
Inventor: TAKAGI KAZUYA
IPC: B41J11/02
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To readily measure a gap between a platen and a print head by a method wherein the print head is sequentially opposed to a plurality of plane faces and a clearance-gauge is inserted into the gaps between the plane faces and print head. SOLUTION: A platen 15 has a plurality of plane faces 25, 26 which are respectively provided to an upstream side region and a downstream side region in a non-printing region in the paper conveying direction. Recess sections 27, 28 are respectively formed on a downstream side of one 26 of the plane faces disposed at the upstream side in the paper conveying direction and on an upstream side of the other plane face 25 disposed at the down stream side in the paper conveying direction. As a result, it is possible to measure a gap between a platen 15 and a print head 20 in a condition that a region at a tip portion of the print head 20 is divided into the upstream side and downstream side in the paper conveying direction.  As a clearance-gauge 30 can be inserted into the gap between the plane face 26 and print head 20 at the innermost portion in the inserting direction irrespective of the inclination of the print head 20 because of the formed recess sections 27, 28, the clearance-gauge 30 can be inserted from the identical direction, thereby raising the operability.

Title: Optical filter
Inventor: WATANABE YASUSHI
IPC: G02B27/46
Filed: 1984-05-17
Abstract: PURPOSE:To improve the picture quality of an applied solid-state image pickup device by passing an incident luminous flux through the first - the third birefringent plates, forming separated luminous fluxes to three luminous fluxes arranged at an equal interval on one straight line, and setting the luminous flux of both ends and the luminous flux of the center to an equal intensity and an intensity of two times of the luminous fluxes of both ends, respectively. CONSTITUTION:With respect to an incident luminous flux l in one Z axis direction, three pieces of birefringent plates C1, C2 and C3 are placed vertically in the Z axis direction, and the thickness in the Z axis direction is set to w1, w1/2<1/2>, and w1/2<1/2> with regard to the refracting plates C1, C2 and C3, respectively. The luminous flux which has passed through the refracting plate C1 is separated into a normal light lo and abnormal light le of an equal intensity. Subsequently, it is separated into normal lights loo, leo and abnormal lights loe, lee by the refracting plate C2. Furthermore, it becomes normal lights loeo, leeo and abnormal lights looe, leoe by the refracting plate C3. Accordingly, the separated luminous fluxes become three luminous fluxes arranged at an equal interval dl on one straight line, and the luminous flux of both ends, and the luminous flux of the center become an equal intensity and an intensity of two times of the luminous flux of both ends, respectively. In this way, by applying this filter to a solid-state image pickup device, its picture quality can be improved.

Title: Bacteriostatic sheet
Inventor: HOSAKA NOBUYOSHI
IPC: A01N59/00
Filed: 1986-05-02
Abstract: PURPOSE:To obtain a bacteriostatic sheet suitable for applying to the surface liable to be wet with water droplets or moisture condensation or the surface placed in a moist environment, by covering a bacteriostatic particle layer having specific bactericidal and adsorptive function with a polymer resin layer, etc., containing fine pores. CONSTITUTION:Bacteriostatic particle 3 having bactericidal and adsorptive function is produced by coating fine porous surface of an activated carbon with calcium oxide, calcium hydroxide or potassium hydroxide coated with porous glass (e.g. pearlite, soda glass, etc.). The particles 3 are bonded with a binder 4 having caking property and the surface of the obtained layer is covered with a layer made of a polymer resin, its fiber, carbon fiber, stainless steel or titanium having fine pores 2. When a bacterial cell is adsorbed or attached to the surface of the layer 1, moisture permeated through the fine pore 2 into the sheet is brought to contact with the bacteriostatic particle 3 to make alkaline water, which is diffused into the fine pore 3 or its circumference while gradually increasing the alkali concentration to exterminate the attached bacterial cell.

Title: Safety valve in overload safety device
Inventor: SHIBATA AKIO
IPC: F16K17/10
Filed: 1981-06-29
Abstract: PURPOSE:To have a rapid valve opening, if an overloading arises at the input port, by opening the valve hole of a pilot valve against the force of pilot spring and by blocking the communication hole of main valve. CONSTITUTION:When an overloading arises at a protector 5 to bring about high pressure in the cylinder chamber 7, the pilot valve element 39 goes apart from the valve seat 32 against the force of spring 43 with the aid of an oil line 17 and a pressure oil chamber 31 to permit the oil in the pilot oil chamber 26b to flow out through the gap between the valve element 39 and valve seat 32, and this oil then returns to the tank 10 pass holes 26a, 26b, a port 18 and an oil line 19. Accordingly, the pressure in the pilot oil chamber 26b sinks rapidly. This sinking of pressure will cause blockade of a communication hole 38 through pressure contact of the blocking valve seat 46 with the main valve element 34, and the pressure in the oil chamber 26b sinks still more rapidly. Therefore the main valve element 34 receives an extremely large relative pressure to be opend rapidly.

Title: Manufacture of thin-film semiconductor crystal layer
Inventor: HASHIZUME TSUTOMU
IPC: H01L21/263
Filed: 1990-04-17
Abstract: PURPOSE:To prevent the damage by a beam in an annealed region by a method wherein the operating range of the beam exceeds a substrate. CONSTITUTION:A silicon layer 32 in 100nm is first formed on the whole surface of a square glass substrate whose one side is 30cm. The scanning range of a laser beam in the X-axis direction is a total of 40cm which has protruded by 5 cm each in the plus direction and the minus direction of the X-axis. Thereby, even when the value of scanning speed in the X-axis direction becomes 0, the silicon layer as a specimen does not exist in the point where the value of scanning speed is 0. As a result, the irradiation of the beam is not concentrated at one point, and it is possible to avoid the damage by the beam. Thereby, a uniform and good-quality annealing operation can be executed.

Title: Inclination angle detector
Inventor: IWAZUKA MASAYUKI
IPC: G01B11/26
Filed: 1983-06-07
Abstract: PURPOSE:To take an accurate measurement of inclination angle over a wide range by irradiating an objective surface with laser light which is parallel luminous flux and photodetecting its reflected light by an image sensor, and detecting the inclination angle as variation in the apparent width of the parallel luminous flux. CONSTITUTION:The laser light from a laser light source 1 is collimated by a collimator 8 into parallel luminous flux to illuminate a surface 3 to be measured, and its irregularly reflected light is photodetected by the image sensor 10. In this case, the spot width on the sensor 10 narrows down when the objective surface 3 slants to left and widens when slanting to right to the contrary. This variation in the spot width on the sensor 10 is processed by a processing circuit 6 and converted into a signal corresponding to the inclination angle, which is displayed on a display circuit 7. Consequently, the variation in inclination angle is detected as variation in the apparent width of the parallel luminous flux, so the inclination angle is measured accurately over a wide range without reference to whether the inclination is large or small.

Abstract: PROBLEM TO BE SOLVED: To provide a judgment method, for a residual stress in a sprayed coating, in which the residual stress inside the sprayed coating can be grasped in a short time by a simple means and in which a preferable spraying condition can be judged easily. SOLUTION: A metal is sprayed on one face of a prescribed thin plate 1 which is annealed completely. On the basis of the deformation of the thin plate after its spraying operation, a compressive stress is judged when the thin plate is convex to the sprayed side, and a tensile stress is judged when the thin plate is concave to the sprayed side. In addition, a stress on an unsprayed face is measured by a strain gage or the like, and the residual stress of a sprayed coating 2 is computed on the basis of a balance to the stress. In addition, the thickness of the sprayed coating 2 is changed, the relationship between the thickness of the coating and the residual stress of the molten sprayed coating is found, and the range of a coating thickness to obtain a desired residual stress is decided on the basis of the relationship.
